I’ve experimented with all of them, except for Wave since it’s not publicly available, though I have signed up for updates and preview =)

My intial impression is that Wolfram Alpha is very cool. It answers questions as opposed to finding results. You ask it for the distance between Sydney and Melbourne. It will find the distance, time by car/plane and a map showing the distance. Ask a question and it gives you one answer with some stats. I actually believe this is the way search engines will be headed. It’s a new way of thinking about search results.

Check out this video which has a good comparison of Wolfram Alpha v Google by ZDNet.

Bing is ok. Microsoft needed to upgrade their Live search, which I never used. I only used it when I searched in IE and I forgot the default setting wasn’t google. Live search just did not look pretty. Google was minimalist. It simply worked and had a great UX (user experience). To be honest, I don’t see myself switching from Google to Bing or Yahoo. Google is too dominant in the world of search right now. In Australia, it has something like 70% market share. I might use Wolfram Alpha to experiment. It’s better for unknown answers and simple queries.

Google Wave

I watched the Developer Google IO preview. Its roughly 80 minutes long and I got through about half of it. Waaaay too long. It’s very ambitious and has the potential to change the game. The potential to change the way we communicate online from email/wiki’s/IM, etc…. I really dig the idea of concurrent editing, because half the time you are simply waiting for the other person to respond on IM. The danger is that it can become a stream of consciousness.

In terms of how I communicate and come up with ideas, I like to have the time to think and reflect and then type it up in a word document or a wiki / blog. If I’m doing concurrent live editing (where people can see my edits and thoughts in real time), I’m really put on the spot to come up with something. I know you can turn this feature off on Google Wave, but this is the danger of concurrent editing and the potential.

I really dig it though. The ability to combine rich media like photos, video, playback. The developer described is as how email would look like if it was developed now! It’s like a cool mashup of blogs, wiki, photo sharing, microblogging, IM, etc…

Mashup with Tokyo google maps and Nintendo Wii. Very Cool. It’s called Tokyo Jogging. The video shows that the Google Map doesn’t load fast enough to keep up with the jogging. The guy looks like he is running forever before he moves to the next section. However, this appears to be how Google maps work. You have to click through and press the arrow button before it moves you to the next section.
